TY - JOUR ID - citeulike:6014977 L3 - citeulike-article-id:6014977 N2 - A comprehensive nanotribological study of a hydrogen-terminated diamond(111)/tungsten carbide interface has been performed using ultrahigh vacuum atomic force microscopy. Both contact conductance; which is proportional to contact area; and friction have been measured as a function of applied load. We demonstrate for the first time that the load dependence of the contact area in UHV for this extremely hard single asperity contact is described by the Derjaguin-Müller-Toporov continuum mechanics model. Furthermore; the frictional force is found to be directly proportional to the contact area.
